First it is necessary to know if only your IP address or a complete netblock or your whole provider is blacklisted. (on which Level a listing persists)
To find this information please query our database before doing anything else.
If your IP address is listed as Level 1, this indicates that it is very likely
you caused the problem yourself, knowingly or not.
Please read the submenus for Level 1 to find out, what could have caused your listing, and how to get removed..

If you are an innocent user you should read this section !!!

If the netblock with your IP address inside is listed as Level 2 or your provider is listed at Level 3, and you do not own the complete IP block or you are not the provider itself, this is a good indicator that you are an innocent user. This means that other customers of your service
provider, or even your service provider themselves, caused that listing by regular abuse.

You NEVER sent spam? - Your system was NEVER an OPEN RELAY or an OPEN PROXY?
Your system was never infected by viruses / worms???

This means your service providerís netblock is blacklisted because someone
else abused it for spamming or for the spreading viruses / worms in recent days!!!

It makes no sense for you to try to fix your service providerís problems.

We recommend you do following:

Send a complaint to your service provider and request him/her to stop any
kind of abuse inside his/her netblock.
Think about it like this: You are paying for access and use of the internet
without any problem. Their actions, or inactions in preventing abuse, mean that the service provider is breaking their agreement with you.
